Evolution & Classification Quiz

1. What is the theory of evolution?

1. All species were created simultaneously and unchanged
2. Evolution only affects plants, not animals
3. Species can transform into any other species within a lifetime
4. Species change over generations through the inheritance of favourable traits, driven by natural selection

2. What is adaptation?

1. A change that occurs within one organism's lifetime due to practice
2. A heritable feature that increases an organism's chance of survival and reproduction in its environment
3. A learned behaviour passed on to offspring
4. The process of two species evolving together

3. What evidence supports the theory of evolution?

1. Fossil record, comparative anatomy, DNA similarities, direct observation of evolution, and biogeography
2. Only DNA comparisons
3. Only the work of Charles Darwin
4. The fossil record only

4. What is speciation?

1. A type of mutation
2. The extinction of a species
3. The identification and naming of species
4. The process by which new species form from existing ones, usually due to isolation and divergent evolution

5. Who developed the modern system of biological classification?

1. Carl Linnaeus
2. Charles Darwin
3. Gregor Mendel
4. Louis Pasteur

6. What is the correct order of the taxonomic hierarchy from broadest to most specific?

1. Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species
2. Domain, Species, Kingdom, Class, Order, Phylum, Genus, Family
3. Kingdom, Domain, Species, Class, Order, Family, Genus, Phylum
4. Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain

7. What are the five kingdoms in the traditional classification system?

1. Animals, Plants, Fungi, Bacteria, Protists
2. Animals, Plants, Fungi, Viruses, Bacteria
3. Animals, Plants, Insects, Microbes, Fungi
4. Mammals, Reptiles, Plants, Fungi, Bacteria

8. What is natural selection?

1. Humans selectively breeding animals for desirable traits
2. Random mutation without environmental pressure
3. The extinction of weaker species
4. The process by which organisms with favourable heritable traits are more likely to survive and reproduce

9. What is a fossil?

1. A living organism that has not evolved for millions of years
2. A type of mineral formed from dead organisms
3. Any old rock formation
4. The preserved remains or traces of organisms from the past, found in sedimentary rock

10. What is an example of observed evolution in modern times?

1. Bacteria developing resistance to antibiotics through natural selection
2. Dogs selectively bred for specific traits
3. Giraffes growing longer necks during their lifetime
4. Humans evolving from chimpanzees directly

11. What does 'binomial nomenclature' mean?

1. Classifying organisms by two observable characteristics
2. Classifying organisms into two kingdoms only
3. Naming organisms based on their number of chromosomes
4. The two-part naming system giving every species a unique Latin name: genus + species

12. What is convergent evolution?

1. The merging of two species into one
2. Two populations of the same species diverging over time
3. Two species evolving mutual dependence
4. Unrelated species evolving similar features independently due to similar environmental pressures

13. What distinguishes a species from other species?

1. They can interbreed and produce fertile offspring
2. They have the same diet
3. They live in the same habitat
4. They look identical to each other

14. What are homologous structures?

1. Identical structures in different species with identical functions
2. Organs that have lost their original function
3. Similar structures in different species inherited from a common ancestor, which may have different functions
4. Structures that evolved independently in unrelated species

15. What is a vestigial structure?

1. A feature that improves fitness significantly
2. A newly evolved feature
3. A structure shared between two unrelated species
4. A structure that has lost most or all of its ancestral function through evolution

16. What is the three-domain system of classification?

1. Bacteria, Archaea, Eukarya
2. Bacteria, Fungi, Animalia
3. Monera, Protista, Eukarya
4. Prokaryotes, Eukaryotes, Viruses

17. What did Darwin observe about finches on the Galápagos Islands?

1. All finches had identical beaks suited to all foods
2. Different islands had finches with beaks adapted to different food sources, suggesting descent from a common ancestor
3. Finches did not vary between islands at all
4. Finches on different islands were completely unrelated species

18. What is mass extinction?

1. The controlled culling of invasive species
2. The extinction of a single species
3. The extinction of all large animals only
4. The rapid loss of a large proportion of all species on Earth in a geologically short time

19. What is coevolution?

1. A single species evolving into two new species
2. Evolution in total isolation from other species
3. The reciprocal evolutionary change in two species that interact closely, each driving the evolution of the other
4. Two unrelated species evolving the same features

20. How does DNA evidence support evolution?

1. All organisms have identical DNA
2. DNA evidence contradicts the fossil record
3. DNA is only useful for identifying living species
4. More closely related species share a higher percentage of their DNA, consistent with descent from common ancestors
